Problem: The graph below shows the distribution of molecular speeds for argon and helium at the same temperature.(a) Does curve 1 or 2 better represent the behavior of argon?

FREE Expert Solution

In the graph:

  • the y-axis is the relative number of particles
  • the x-axis is the molecular speed.
    • Molar mass of gas as being related to the number of particles ( molar mass =  particles).


The molecular speed of a gas is given by:

mol. speed=3RTM

where R = gas constant, T = temperature, and M = molar mass of the gas
